Calculate the magnitude of the net force needed to bring a 26,700-kg truck moving at 21.0 m/s to a stop in a distance of 355 m.

a) 139,805 N
b) 156,780 N
c) 167,790 N
d) 178,800 N

Answer :

Final answer:

To calculate the magnitude of the net force needed to stop the truck, use the work-energy principle to find the correct answer, 167,790 N. This principle relates the net force to the change in kinetic energy of the truck. So the correct option is c) 167,790 N.

Explanation:

To calculate the magnitude of the net force needed to stop the truck, use the work-energy principle to find the correct answer, 167,790 N. The magnitude of the net force needed to bring a truck to a stop can be calculated using the work-energy principle.

This principle states that the work done by the net force is equal to the change in kinetic energy of the truck. In this case, the work done by the net force is equal to the kinetic energy of the truck initially, as it comes to a stop. By setting up the equation and solving for the net force, the correct option is 167,790 N (c).
